The FTSE All-World Index is a market-capitalisation weighted index representing the performance of the large and mid cap stocks from the FTSE Global Equity Index Series (GEIS). The index targets 90% coverage of the 9 regions used to construct the GEIS universe. The index covers Developed and Emerging markets and is suitable as the basis for investment products, such as funds, derivatives and exchange-traded funds.

FTSE GEIS provides All Cap, Large Cap, Mid Cap, Small Cap and Micro Cap indices for every covered country and region. Aggregate indices combine size segments as follows:

All Cap = Large + Mid + Small.

All-World (FTSE All-World Index Series) = Large + Mid.

Total Cap = Large + Mid + Small + Micro.

The FTSE All-World Index is maintained as part of the FTSE GEIS universe, using a structured, region-relative process designed to reduce the dominance of the world’s largest markets and improve representation of smaller markets.

At a high level, the index review process screens eligible stocks, assigns each company to a country and region, ranks companies by size, applies investability screens, and then sets index weights using available shares adjusted for free float and foreign ownership limits.

Step 1 — Screen and classify: stocks from 45+ markets are screened for eligibility and classified as Developed, Advanced Emerging or Secondary Emerging.

Step 2 — Assign nationality: each company is assigned to a single country based on factors such as incorporation, tax domicile and headquarters location.³

Step 3 — Rank and size-segment: companies are grouped into nine regional universes, ranked by total market cap and allocated to size tiers using regional cut-offs and buffer zones to help reduce unnecessary turnover.

Step 4 — Apply investability screens: screens remove securities considered unavailable to institutional investors.

Step 5 — Set weights: weights are market-cap based and adjusted for free float, foreign ownership restrictions and minimum foreign headroom requirements.

FTSE GEIS and the FTSE All-World Index changes are implemented quarterly, with the full regional universe and liquidity reviews conducted semi-annually. Review-driven changes are implemented after the close on the third Friday of March, June, September and December.

Semi-annual reviews (March and September): establish each regional universe using data as of the prior quarter-end (e.g. September review uses June month-end data).

Companies are valued and ranked by full market capitalisation (price x shares in issue). Where there are multiple lines of equity capital in a company, all of them are included and priced separately, provided they pass index eligibility screens in their own right. Market caps are aggregated when evaluating size index membership.

The index constituents are then selected for each size segment using market cap cut-offs. To reduce turnover, existing and potential constituents are subject to a series of ‘buffer zones’ to determine the cut- off points between Large, Mid, Small and Micro Cap. The FTSE All-World Index includes Large and Mid Cap constituents in the FTSE GEIS universe.

Liquidity testing: each security is tested using the monthly median of daily trading volume; size cut-offs are applied with buffer zones between tiers.

Quarterly reviews (June and December): address events such as IPOs, changes in shares in issue, free-float changes and ICB classification changes.

Changes outside scheduled reviews: corporate actions and significant-sized IPOs can trigger additions or deletions between reviews.

Within the FTSE GEIS universe, size segments are determined by ranking eligible constituents within each region and applying percentage bands, with buffer zones to help minimise turnover.

At the regional review, the top 98% of the regional universe becomes the index universe. Within that eligible universe: top 70% = Large-cap; next 20% = Mid-cap; final 10% = Small-cap (subject to buffers).

The FTSE All-World Index includes the Large-cap and Mid-cap component of FTSE GEIS.
